best place is mcmaster.com search item #5648k23, same stuff as alamo city p.b. but mcmaster is .19 a foot (min 25 ft length) but comes up to $9.54 with shipping for 25 ft, alamo city is 6.50 with shipping for 1 foot, its the same stuff, i've read other threats on here and made sure, all specs are the same. I ordered saturday and it showed up at my door today (monday) so well worth $5.00 shipping
